Explanation:
Problem 1
Jenna walks 1 mile in 12 minutes
This means that she covers 1/12 th of a mile in one minute
The equation that represents this problem is
y = (1/12)*x
Where y is the number of miles covered, and x is the walking time in minutes.
If she walks 48 minutes, she will travel y = (1/12)*48 = 4 miles
Problem 2
Loaf of bread ----> $2
4 bags of vegetables -- > Price unknown
TOTAL AMOUNT SPENT
y = 4*x + 2
Where y is the amount spent in dollars, and x is the price per one bag of vegetables.
Problem 3
$1 per glass of lemonade
$9 dollars per supply
y = 1*x - 9
Where y is the amount obtained in dollars, and x is the number of glasses of lemonade sold.
if y >0, she will make profit, (y>9) This means she needs to sell 10 glasses
Problem 4
Assuming that John's dad doubles the amount John makes each week.
The expression is
y = 2*x
Where y is the amount obtained in dollars, and x is the amount saved by John himself each week.
Problem 5
The donor is giving Christina 2 dollars per mile
The expression that represents this condition is
y = 2*x
Where y is the amount obtained in dollars, and x is the number of miles traveled.
Problem 6
For each pound collected, Kenna will receive $1.50
The expression that represents this condition is
y = (1.5)*x
Where y is the amount obtained in dollars, and x is the number of pounds of magazines collected.
Problem 7
Graham made 7 pennants in an hour. Based on this relation, He will make 14 in two hours and 21 in three hours.
The expression that represents this condition is
y = (7)*x
Where y is the amount of pennants made, and x is the number of hours worked on a day.
Problem 8
Maddy earns $12 per hour. Based on this relation, she will make $24 in two hours and $36 in three hours.
The expression that represents this condition is
y = (12)*x
Where y is the amount obtained in dollars, and x is the number of hours worked in a night.
Problem 9
Steven practices his trumpet for 30 min each day. The amount of time practiced is given by the following relation
y = 30*x
Where y is the amount of time practiced in minutes, and x is the number of days of the month that he practiced in.
Problem 10
Determine whether the statement is true or false
In m + 8, the variable m can have any value.
Since there are no restrictions imposed on the value of m, and the expression is not part of a certain equation or condition, the statement is TRUE. m can have any value
